Leupold's Duplex reticle has heavy posts to help the reticle to stand out in low light conditions. It also has thin cross hairs in the center to prevent obstructed view of the target. This optic also features Leupold's CDS-ZL2 (Custom Dial System ZeroLock 2). This locks the dial in place to prevent it from being accidentally turned from zero. This also features the Firedot Illuminated Reticle, which includes Motion Sensor Technology (switches reticle to standy-by mode after five minutes of inactivity, in order to preserve battery life; re-illuminates with the touch of a button).
